NETBUGGER3
NETBUGGER3 is a third level program for the debugging of second and
third level programs, experimentation with and simulation of third
level protocols.
We were writing an RJE FILENET to interact with UCLA-CCN, and
discovered that they (UCLA-CCN) wouldn't be up for a few months. We
needed a program that would simulate CCN, so that we could interact
with it and debug our FILENET. It occurred to me that all over the
network, people had similar problems, i.e., they couldn't debug
programs because the intended server wasn't up. And so I started to
write a third level debugger-simulater.
With NETBUGGER3 the user can easily issue RTSs, STRs, and LISTENs,
interrogate the status of connections, receive and display NCP-USER
events and transmit and receive data over as many as twelve
connections (per copy of program running). Received data can be
displayed in ASCII, EBCDIC on HEX. The user can, of course,
originate data for transmission in the same forms. NETBUGGER3 can be
initiator, receiver and/or intermediate in connections.
An example of how NETBUGGER3 could be of use to other hosts on the
Net follows.
Host X has a special third level Filenet to debug. The host they
plan to interact with won't be up for several months. Host X can
arrange with us to interact with NETBUGGER3, which will simulate the
proposed third level protocol and transactions.
An alternate possibility is for Host X to use his Telnet to enter our
system and start NETBUGGER3 himself. He can then be running
NETBUGGER3 on one console and his filenet on another.

RFC 162 NETBUGGER3 May 1971
Then, later on when the other server Host is up, NETBUGGER3 can be
used an intermediate between Host X and his serving host. Every
message from Host X to server and vice versa can be displayed,
examined and, if necessary, edited as it passes through the
NETBUGGER3 console, thus making possible the debugging and
measurements.
This is only one example. If you are interested in using, receiving,
documentation, making suggestions or anything else regarding
NETBUGGER3, please contact the Network liaison at UCLA - NMC.
